in CCNA & CCENT
Hello to everyone on the forum. my current issue is with learning to subnet. WoW, what a topic, it seems a bit difficult at this point, probably because i am new to it. Anyway, I could really use some help in learning subnetting. I understand much about ip address classes and the default subnet masks as well as the binary number system. What is really giving me a problem is understanding the range of host addresses after i have determined the subnet increment value. Any help is greatly appreciated, thanks!
One of the main problems, i find myself trying to understand about subnetting is figuring out and interpreting the range of host addresses for each subnet based on a particular class of ip address. I understand how to determine the number of subnets you can create by using the powers of two and the number of bits used for subnetting borrowed from the host portion of the mask, and then based on the number of remaining host bits determine the number of hosts per subnet. I am clear on that part, but again trying to understand the range of host addresses per subnet is whats giving me a problem. Any comments / help is much appreciated. Thanks!

The Todd Lammle Sybex book is an amazing book for subnetting. Once you know this chapter well, read the Cisco Press Subnetting chapter. Make sure you read Sybex first though -

You really just need to
1; find a subnet how to
2; find a website that will spit out random subnet questions to you for as long as you can handle to study it.
It is seriously simple. I was like you and had a major problem with it until I sat down one night and blew away about 4-5 pages of problems.
What annoys me about the CCNA is the no subnet zero. I think it was so stupid of them to allow no zero subnets, when they're all over the place in real life. Be wary of that when you start studying. Some of the practice sites I went to require subnet zero answers (192.168.1.0), but the CCNA does NOT. -

Here's a site where you can practice subnetting.
It'll give you random IP addresses and SNMs.
You have to type in the Network, First, Last, and Broadcast addresses.

Hope this helps.
